SPECIFICATION forming part of Letters Patent No. 600,633, dated March15, 1898.

Application filed November 4,1896. erial No. 611,013. (No model.)

To all whom it may concern:

Be it known that I, JOHN CLAYTON, a citizen of the United States,residing at Ouyahoga Falls, in the county of Summit and State of Ohio,have invented certain new and use ful Improvements in Trolleys; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to electric trolleywheels.

I-Ieretofore considerable difliculty has been experienced in usingtrolley-wheels, owing to the fact that frequent lubrication wasnecessary in order that the wheel might run smoothly. Another difficultyhas also been experienced, as the trolley-wire is liable to jump thetrolley-wheel when the car is moving rapidly or going around a curve.

The object of my invention is to provide a novel form of trolley-wheelwhich will be selflubricating for a comparatively long period of time,thereby doing away with the expenditure of time and labor.

A further object is to provide improved means adapted to prevent thetrolley-wire from jumping the wheel.

Having these objects in view, the invention consists in the combination,with a trolleywheel, of a hollow bearing therefor, which is adapted tohold a lubricant and is provided with outlets, so that the lubricantwill be delivered to the bearing-surface of the wheel as the latterrevolves. V

The invention further consists in certain improved guards adapted toprevent the trolley-wire from jumping the wheel; and it further consistsof certain other improved features and novel combination of partsappearing more fully hereinafter.

In the accompanying drawings, Figure 1 is a side elevation, Fig. 2 anend view, Fig. 3, a cross-sectional view, and Fig. 4 a detail View, ofthe hollow bearing for the wheel, the latter being removed, said viewdisclosing one pair of lubricating grooves.

The numerals 1 and 2 designateduplicate sections or halves of the head,and these clasp around and are secured to the trolley-pole 3. Thesections of this head are provided with hollow bearing-sections i and 5,said sections being form ed integral with the respective sections of thehead. Each bearing-section is provided with opposite lubricating-grooves6 and 7, which slant downwardly. These grooves are deepest at the inneredge of the section, wherea semicircular hole 8is formed, which leadsinto the interior of the section. It will thus be observed that when thebearing-sections abut on each other there are provided two circularholes 9 and 10, through which the lubricant contained within thebearing-sections can find its way out into the grooves.

The numeral 11 designates the trolleywheel, which is snugly yet easilyreceived on the bearing-sections. At 12 is shown a bolt which passesthrough the bearing-sections from side to side of the headand isprovided with a nut 13 on its ends. The lubricant employed should besolid or substantially so, and it is introduced in the bearing-sections,the latter projected into the trolley-wheel, and then the parts areclamped together by the bolt and nut. As the wheel revolves thelubricant passes out through one of the circular openings and into theinclined grooves that lead therefrom, so that said lubricant isdistributed over the entire width of the bearingsurface of thetrolley-wheel. Of course it is obvious that as many of the openings andlubricating grooves could be employed as found desirable; but I findthat two sets are generally sufiicient, and hence have only spoken ofthat number. The capacity of the bearing-sections being quite great, thewheel will be self-lubricating for a number of days.

I will now proceed to the description of the means adapted to retain thetrolley-wire on the wheel. Connected to each section of the head thereis a curved or arc-shaped guard 14:, and this guard lies immediatelyoutside the faces of the wheel and projects up above the peripherythereof. It can be made of any desired width and is well adapted toguiide the trolley back into the wheel should it jump from the latter.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination with head sections adapted for connection to thetrolley-pole, of hollow bearingsections connected to said municationwith the interior of the bearing-v sections, and a trolley-wheel mountedon said bearing-sections.

3. The combination with head sections adapted for connection to thetrolley-pole, of

hollow bearing-sections connected thereto and projecting inwardly andmeeting, said sections being adapted to contain the lubricant, eachbearing-section being provided with an inclined lubricating-groove whichleads from the edge of the section laterally, said grooves beingdisposed in sets which meet at the edges of the bearing-sections, atrolley-Wheel mounted on said bearing-sections, and means for holdingthe head-sections together.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JOHN CLAYTON.
